1. How to select a suitable laser distance sensor for your application?
Welcome to the Xi'an Zhizun International Trade Co., Ltd.
Learn about laser distance sensor
To select a suitable laser range sensor, you need to consider the following factors
1) Measuring range
Determine the range you need to measure.
2) Measuring precision
The laser sensor is generally accurate to the millimeter or the centimeter level, which can be selected according to your accuracy.
3) Measuring frequency
It needs to be selected according to the target you are measuring. The high frequency is generally for moving objects, and the low frequency is suitable for stationary objects.
4) Other factors
Many factors will affect the measuring result, such as air visibility, ambient light and temperature range of the environment in which the laser distance sensor is used, color and smoothness of the measured target, cleanliness and smoothness of laser emission lens and protection glass, etc.
2. How to use a laser distance sensor?
To measure the distance between two objects, firstly place the sensor at one of the objects, then let the laser beam of the sensor aims at the target. The laser sensor can calculate the distance between the target and laser sensor according to the laser time-of -flight principle.
3. How does a laser distance sensor work?
A laser sensor emits a laser beam to an object surface, then the laser beam bounce off the object and returns to the sensor. Because the speed of the light is known, the sensor uses the time it took for each send to return to the sensor to calculate the distance it traveled.
